Notice that these two numbers effectively divide up the number line into three regions: Now, choose a number in each of these regions and put it back in the factored inequality to see which cases are true. And that's essentially describing the solution set for this quadratic inequality here. Before we get to quadratic inequalities, let's just start graphing some functions and interpret them and then we'll slowly move to the inequalities. A Quadratic Equation in Standard Form ( a , b , and c can have any value, except that a can't be 0.) Solving linear inequalities, such as "x + 3 > 0", was pretty straightforward, as long as you remembered to flip the inequality sign whenever you multiplied or divided through by a negative (as you would when solving something like "–2x < 4").. Our discriminant is therefore: 1. There is a big jump, though, between linear inequalities and quadratic inequalities.

Because the solution is only negative in the interval , that must be the solution. Rewrite the equation in standard form. Since this is not less than zero, the solution to the inequality cannot be found in this region. Since this is not less than , the solution to this inequality cannot lie in this region. This is a quadratic inequality. Since the original inequality was less than or equal, we include the endpoints. The given equation is not in that form however, so we must first multiply it out to get it into that form. Since this solution is greater than or equal to , the solution can be found in this region. Overview of Quadratic Inequalities Chapter Exam Instructions. Since this number is not less than zero, the solution cannot lie in this region. Aptitude Questions – Inequalities Set 1. Use the quadratic formula to find critical values: s = − ( − 4) ± √ ( − 4) 2 − 4 ( 1) ( 6) 2 ( 1) = 4 ± √ 16 − 24 2 = 4 ± √ − 8 2. Since this number is less than zero, the solution can be found in this region. You must answer the questions in the spaces provided.
